Not worried for two reasons:
1. Ain't happening.
2. Teams' attempts to make themselves into instant winners doesn't usually work, witness the Eagles "Dream Team". How'd that work out?
Bucs did it with Brady, obviously, but that's an aberration, Bucs already had top weapons like receivers, WFT doesn't. I've no doubt Rodgers would put them as division winners, but don't think he'd be able to bring them to a SB win, Rodgers can only do so much. GB has had decent teams since 2011, but the "elite" Rodgers didn't get them to the SB either...
